I have turned on snapping in Discover3D, but still cannot snap to the object
Solution
1. Make sure the selectability is enabled in the layer control. Note that 3D vectors, such as DXF files, cannot be selectable. These can be converted to a Feature using Features>Import, which then can be selected
2. Make sure the Cursor plane is bonded to the layer you wish to snap to. I this mode the 2D plane disappears, and cross hairs will appear as you hover on the points or DEM
